Abstract

Abstract: Nonlinear intersymbol interference is one of the important factors affecting the satellite channel, and it is very necessary to eliminate and reduce the effect. On the basis of using the Volterra series decomposition to denote the nonlinear channel, linear Minimum Mean Square Error (MMSE) based Volterra channel turbo equalization algorithm was proposed. In this proposed algorithm, after the linear MMSE equalizer and its two approximation algorithms were derived, the proposed linear MMSE based Volterra channel turbo equalization exact and approximate algorithms could not only eliminate the linear and nonlinear intersymbol interference but also reduce the computation complexity. Simulation results show the effectiveness of the proposed algorithm.
